摘要
为探究山东渤海滨海地区互花米草时空分布特征,本研究选用Landsat遥感影像,基于支持向量机(SVM)算法对山东渤海滨海地区互花米草开展动态监测。结果表明:①2010年、2015年和2019年山东渤海滨海地区互花米草分布面积分别为20.33km2、22.34km2和48.77km2;②互花米草主要分布于黄河三角洲地区、五号桩东部海岸、孤东油田东北角和小清河河口附近等,且在不同区域呈现不同的空间分布特征。
In order to explore the spatiotemporal distribution characteristics of spartina alterniflora in the coastal area of Shandong Bohai Sea,this study selected Landsat remote sensing images and conducted analysis based on support vector machine(SVM)algorithm.The results show that:①In 2010,2015,and 2019,the distribution areas of Spartina alterniflora in the coastal areas of Shandong Bohai Sea were 20.33km2,22.34km2,and 48.77km2,respectively;②Spartina alterniflora is mainly distributed in Yellow River Delta,the eastern coast of pile 5,the northeast corner of Gudong Oilfield,and near the Xiaoqing River estuary,and presents different spatial distribution characteristics in different regions.
